Definitions
- the present invention relates to a drive system for an exhaust gas flap of a vehicle exhaust gas system.
- exhaust gas flaps are used in connection with cylinder deactivations.
- the exhaust gas pipes that are associated with the cylinders that are to be deactivated are closed by means of exhaust gas flaps.
- Exemplary exhaust gas flaps and their drive systems are disclosed in DE 10 2009 016 597 A1, WO 2015/078432 A1, DE 10 2009 013 815 A1 and also DE 10 2011 107 088 A1.
- Coupling elements that connect the adjustment drive and the exhaust gas flap are generally loaded in two ways. On the one hand, it is necessary for the coupling elements to transfer torque from the adjustment drive to the exhaust gas flap in order to open and to close the exhaust gas flap. On the other hand, an axial force is applied by way of the coupling element to the mounting arrangement of the exhaust gas flap. The axial force is necessary in order to seal the spindle feedthrough of the exhaust gas flap. Furthermore, vibrations that make themselves noticeable acoustically as rattles are avoided via the axial force.
- the aim is to embody the transfer path of the torque as rigidly as possible in order to be able to move the exhaust gas flap as precisely as possible and in such a manner that causes few vibrations.
- a high rigidity causes a high friction on the spindle feedthrough of the exhaust gas flap, and thereby a mechanical load of the associated sealing arrangement and also an increased resistance when moving the exhaust gas flap.
- the aim is therefore to embody the axial coupling as less rigid, in other words as more elastic.
- the object of the present invention is therefore to provide a drive system for an exhaust gas flap in which the coupling of an adjustment drive to an exhaust gas flap is rigid for the transfer of torque and is flexible for axial movements.
- a drive system for an exhaust gas flap of a vehicle exhaust gas system said drive system having a drive element and an output element, wherein the drive element is provided for the purpose of being connected to an adjustment drive and the output element is provided for the purpose of being connected to an exhaust gas spindle.
- a resilient element is provided that is arranged between the drive element and the output element and comprises a center section and two end sections.
- the center section is used to transfer torque between the drive element and the output element, and both the center section as well as the two end sections are coupled to the same component of the two elements: drive element and output element.
- multiple sections of the resilient element namely the center section and the two end sections are connected to the same component, in other words either to the drive element or to the output element.
- the other of the two elements is connected to another section of the resilient element so that torque can be transferred from the drive element to the output element.
- the construction in accordance with the invention is technically simple and cost-effective.
- the resilient element represents a reliable and cost-effective possibility for coupling the drive element and the output element.
- the resilient element can be constructed in a rotationally symmetrical manner.
- the center section of the resilient element is preferably embodied as a straight section.
- the center section is connected by way of two connecting sections to the end sections, and the connecting sections are used to transfer torque between the drive element and output element, wherein the connecting sections are coupled to the output element or the drive element.
- the resilient element is, in other words, constructed in a symmetrical manner. As a consequence, there is a uniform loading of the components of the drive system for an exhaust gas flap, which results in a high functional reliability and an increased serviceable life.
- the transfer path of torque between the drive element and the output element comprises the center section and the connecting sections. If the center section is coupled to the drive element, the connecting sections are coupled to the output element. In the reverse case, if the center section is coupled to the output element, the connecting sections are coupled to the drive element.
- the resilient element can in other words be arranged in two orientations. The fact that two connecting sections are provided leads to a reliable and uniform transfer of torque.
- the connecting sections in each case engage in a slot that extends parallel to the axis of rotation of the drive element or the output element.
- the transfer path for the torque is thereby divided into two paths, which reduces the load peaks in the drive system.
- the serviceable life of the drive system increases.
- the connecting sections are guided in the slots in the direction of the axis of rotation of the drive element or the output element.
- the connecting sections can transfer torque by way of the walls of the slot.
- the base of the slot or a geometric shape in the walls of the slots represents a stopping element or abutment for the connecting sections in the axial direction.
- the connecting sections are mounted in the slots in such a manner that said connecting sections can be moved in a direction perpendicular with respect to the axis of rotation slightly along the walls of the slots.
- the slots are arranged in a U-shaped receiving element and are located in the arms of the U-shape, wherein the slots are preferably open on one side.
- a simple assembly of the connecting sections is possible by virtue of the slots being open on one side.
- the arrangement in the U-shape furthermore causes a uniform loading of the components of the drive system.
- the receiving element can, for example, be a press-bent part of sheet metal or a synthetic material.
- the receiving element can be fixedly connected to the drive element or the output element.
- the connecting sections comprise, in each case, two resilient sections that extend essentially adjacent to one another and comprise a resilient section that connects said resilient elements, wherein the resilient section is preferably a resilient bow.
- the connecting sections are consequently produced in a manner that saves materials and are therefore light in weight.
- the connecting sections essentially have the shape of a U, wherein the resilient sections that extend adjacent to one another represent the arms of the U.
- the resilient sections that extend adjacent to one another can extend parallel or inclined towards each other and can lie on the walls of the slots.
- the connecting resilient section represents the base line of the U-shape.
- the connecting resilient section can be embodied as round, with corners or having a free geometric shape.
- the center section and the connecting sections lie in a plane and the end sections lie in a plane that is spaced therefrom. It is possible to produce the resilient element in a simple and cost-effective manner by virtue of this embodiment. Simultaneously, the planar shape renders it possible to have a cost-effective mounting arrangement and handling procedure. It is possible by way of the spacing of the planes to set the resilient paths that are to be available to the resilient element. Furthermore, the end sections and the center sections can be adjusted to different embodiments of the drive system for an exhaust gas flap.
- the center section engages in a groove that is provided on the drive element or on the output element, wherein the longitudinal axis of the groove extends in a transverse manner, and in particular, in a manner perpendicular with respect to the axis of rotation of the drive element or the output element.
- the groove represents a possibility that is easy to produce of coupling the drive element or the output element to the resilient element so that torque can be transferred.
- the torque is transferred from the walls of the groove to the center section or in reverse.
- the center section preferably does not lie on the groove base.
- the center section of the resilient element is preferably embodied geometrically slightly longer than the groove.
- the resilient element can consequently be displaced slightly along the groove. It is thus possible in a simple manner to compensate for a possible axis offset between the exhaust gas flap spindle and the adjustment drive. The drive is consequently prevented from jamming.
- the center axis of the hole preferably extends in a transverse manner, and in particular, in a manner perpendicular with respect to the longitudinal axis of the groove.
- the groove and the hole can intersect.
- a simple, cost-effective but reliable coupling of the resilient element to the drive element or the output element is ensured. This coupling can likewise be achieved, in particular if the groove and hole intersect, in the tightest of spaces.
- the two end sections engage into the groove, wherein the end sections lie on the groove base. Both the end sections as well as the center section are then mounted in the same groove. The end sections and center section thereby lie in a plane. It is not necessary to provide a hole in this embodiment, which reduces production costs.
- the center section of the resilient element can be reinforced or can be embodied in a multi-layered manner. This is achieved as a consequence of a greater rigidity of the center section, which causes a greater rigidity of the transfer path for torque.
- the end sections can remain single-layered or not reinforced so that the rigidity of a transfer path is proportionally low for an axial coupling.
- a rigidity of the resilient element for transferring torque between the drive element and the output element is greater than a rigidity of the resilient element for axially coupling in a resilient manner the drive element and the output element. Since different sections of the resilient element are provided for the transfer of the torque and the transfer of axial forces, an independent setting of the rigidity with regard to these two load types is possible.
- the high rigidity for transferring torque is achieved by the center section and the connecting sections.
- the exhaust gas flap can thereby be positioned precisely in a closed state, in an opened state, and any state lying between the closed and open states. Simultaneously, a high rigidity prevents rotational vibrations of the exhaust gas flap.
- the lesser rigidity for providing the axial resilient coupling arrangement is achieved by means of the end sections.
- the resilient element is produced from a resilient wire.
- the resilient element can thereby be produced in a cost-effective manner and in large quantities.
- the production can, in particular, occur by bending a single resilient wire piece, which is a well-known and widely used production method.
- the resilient element can thereby be constructed in the following manner when viewed from one end of the resilient wire to the other end: end section, connecting section, center section, connecting section, end section.
- the connecting sections are embodied in each case from a first of the resilient sections that extend adjacent to one another, a connecting resilient section, and a second of the resilient sections that extend adjacent to one another.
- the resilient element can be constructed in a rotationally symmetrical manner.
- the resilient element in a plan view is in the shape of an eight, wherein the center section forms a center section of the eight and the connecting sections essentially form the outer contour of the eight.

- a hole 32 having a center axis 34 is arranged in the shaft end, said hole 32 extending essentially in a manner perpendicular with respect to the groove 26 and intersecting said groove 26 in the illustrated exemplary embodiment.
- the output element 16 and the exhaust gas flap spindle 8 are illustrated in FIG. 2 and FIG. 3 .
- the two are connected to one another in such a manner that they cannot rotate.
- the sectional plane is selected in FIG. 2 in such a manner that the axis of rotation 20 is included.
- the exhaust gas flap 22 that is connected in a non-rotatable manner to the exhaust gas spindle 8 is simultaneously rotated in the sectional plane.
- the output element 16 comprises a U-shaped receiving element 40 having two arms 42 , 44 .
- the two arms 42 , 44 are provided with, in each case, one slot 46 , 48 , wherein the two slots 46 , 48 extend parallel to the axis of rotation 20 and are open on one side. In FIG. 2 , the side of the slots 46 , 48 that is facing the adjustment drive 12 is open.

- the connecting section 52 is embodied from two resilient sections 60 , 62 that extend adjacent to one another and are connected by way of a resilient section 64 .

- the center section 53 of the resilient element 18 also forms a center section of the eight.
- An outer contour of the eight is represented by the connecting sections 51 , 52 .
- connecting section 51 , the center section 53 and also the connecting section 52 lie in a first plane.
- the end sections 49 , 50 lie in a second plane that is spaced from the first plane (cf. FIG. 5 ).
- the resilient element 18 can be constructed in a rotationally symmetrical manner.
- the axis of rotation corresponds in the installed state to the axis of rotation 20 .
- FIG. 6 An alternative embodiment of the resilient element 18 is illustrated in FIG. 6 .
- the center section 53 is embodied as two-layered, as a result of which the rigidity of the center section increases.
- the end sections 49 , 50 are not reinforced, in other words are embodied as single-layered.
- the resilient element 18 is coupled to the drive element 14 in such a manner that the center section 53 is received in the groove 26 of the drive element 14 .
- the center section 53 is guided from the walls of the groove 26 and can move in the direction of a groove depth since said center section 53 does not lie on the base of the groove 26 .
- center section 53 is slightly longer than the groove 26 .
- the center section 53 can therefore be displaced in the groove 26 in order to compensate for an axis offset that may be present. This is the case if the adjustment drive 12 and the exhaust gas flap spindle 8 are not arranged on a common axis of rotation 20 .
- the end sections 49 , 50 are likewise coupled to the drive element 14 .
- the end sections are received in the hole 32 .

- An axis offset can consequently be compensated for in this direction, said axis offset occurring if the adjustment drive 12 and the exhaust gas flap spindle 8 are not arranged on a common axis of rotation 20 .
- the displacement direction of the center section 53 is essentially perpendicular to the displacement direction of the connecting sections 51 , 52 .
- This pressure force F is initially transferred by way of the peripheral surface of the hole 32 to the end sections 49 , 50 of the resilient element 18 .
- the pressure force F is not transferred to the center section 53 of the resilient element 18 since said center section can be displaced freely in the groove 26 in the direction in which the pressure force F acts.

- the pressure force is received with an axial stop in the U-shaped receiving element 40 .
- the pressure force F is transferred by way of this stop from the resilient element 18 to the U-shaped receiving element 40 and in turn from said receiving element 40 to the output element 16 .
- the drive element 14 transfers by way of the walls of the groove 26 the torque M to the center section 53 of the resilient element 18 . Since the hole 32 is embodied as clearly larger in diameter than the diameter of the end sections 49 , 50 of the resilient element 18 , torque M is not transferred by way of the end sections 49 , 50 .

- the connecting section 51 , the center section 53 and also the connecting section 52 lie in a first plane.

- the center section 53 and the end sections 49 , 50 are embodied in such a manner that they can be displaced slightly along the groove 26 in order to be able to compensate for a possible axis offset that occurs if the adjustment drive 12 and the exhaust gas flap spindle 8 are not arranged on a common axis of rotation 20 .
- This pressure force F is initially transferred by way of the groove base of the groove 26 to the end sections 49 , 50 of the resilient element 18 .
- the pressure force F is not transferred to the center section 53 of the resilient element 18 since said center section can be displaced freely in the groove 26 in the direction in which the pressure force F acts.
- the pressure force F is then transferred to the connecting sections 51 , 52 of the resilient element 18 .
- the interaction with the U-shaped receiving element 40 then occurs as in the first-mentioned exemplary embodiment.
- the drive element 14 transfers by way of the walls of the groove 26 the torque M to the center section 53 and to the two end sections 49 , 50 of the resilient element 18 .
- the torque M is introduced into the connecting sections 51 , 52 .
- the interaction with the U-shaped receiving element 40 then occurs as in the first-mentioned exemplary embodiment.
- the drive element 14 can also be coupled to the output element 16 in the kinematic reversed manner.
